Introduction to ASME B1.2 Standard and 1.75-16UN-2A Thread Ring Gauge

The ASME B1.2 standard governs the specifications for Unified Screw Threads (UN/UNR) and their gauging systems, ensuring interchangeability and precision in mechanical assemblies. Under this standard, the 1.75-16UN-2A thread ring gauge is designed for inspecting external threads with a nominal diameter of 1.75 inches, 16 threads per inch (TPI), and a 2A tolerance class (medium fit for external threads). This gauge ensures that the threaded component meets critical dimensional requirements, including pitch diameter limits and thread form accuracy, as outlined in ASME B1.2.

Key features of the 1.75-16UN-2A thread ring gauge include:

• Tolerance Compliance: The 2A class specifies a medium allowance for external threads, balancing manufacturing feasibility and functional reliability.

• Durability: Manufactured from high-grade materials like GCr15 bearing steel, these gauges resist wear and maintain precision over repeated use.

• Application: Widely used in aerospace, automotive, and heavy machinery for verifying UN-series threads.

Sowant Precision Gage: Custom UN-Series Thread Gauges

Sowant Precision Gage specializes in producing ASME B1.2-compliant UN-series thread ring/plug gauges with exceptional advantages:

1. Rapid Lead Time: Leveraging advanced CNC thread grinding technology, Sowant ensures delivery within 30 days, even for custom orders.

2. High Precision: CNC machining guarantees tolerances within ±0.003 mm, critical for industries demanding tight thread fits.

3. Cost Efficiency: Competitive pricing without compromising on material quality or surface finish (e.g., chrome-plated options for corrosion resistance).

4. Customization: Capable of producing non-standard diameters, pitches, and tolerance classes (e.g., 1A, 3A, or 3B).
